Is it possible to prevent errors in a looping round script with a giant pcall?

If, in some bizarre case, you have a looping round script and it breaks, your entire game is on freeze. Forever! In that case, could you possibly wrap said round script in a giant pcall as follows?

function mainRoundSequence()
	while wait() do
		-- intermission
		wait(10)
		-- load map
		wait(5)
		-- load characters
		wait(30)
		-- round over
		wait(5)
		-- articulate the round stats, start over.
	end
end

while wait(1) do
	success, err = pcall(function()
		mainRoundSequence()
	end)

	if err then print(err) end
end

Again, would this script theoretically work to make your script "break-proof"? Thanks in advance.
